Access elasticsearch and kibana remotely?

Hi,

This might not really belong here, but maybe its related to the security features of opendistro.

I installed it, and want to access elasticsearch and kibana from a remote machine using the browser:
https://1.2.3.4:9200

I get a timeout. It works on localhost though.
I had this when I tried stock elasticsearch without any security features. The solution there was to add network.host: 0.0.0.0 to the config file.
But if I do this here, I get an error when restarting the elasticsearch service.

Any tips? Thank you!
